Populations inhabiting the bioclimatic edges of a species＇ geographic range face an increasing amount of stress from alterations to their environment associated with climate change. Moose Alces alces are large-bodied ungulates that are sensitive to heat stress and have exhibited population declines and range contractions along their southern geographic extent. Using a hidden Markov model to analyze movement and accelerometer data, we assigned behaviors （rest, forage, or travel） to all locations of global positioning system-collared moose （n = 13, moose-years = 19） living near the southern edge of the species＇ range in and around Voyageurs national Park, Mn, USA. We assessed how moose behavior changed relative to weather, landscape, and the presence of predators. Moose sig- nificantly reduced travel and increased resting behaviors at ambient temperatures as low as 15~C and 24~C during the spring and summer, respectively. In general, moose behavior changed season- ally in association with distance to lakes and ponds. Moose used wetlands for travel throughout the year, rested in conifer forests, and foraged in shrublands. The influence of wolves Canis lupus varied among individual moose and season, but the largest influence was a reduction in travel during spring when near a wolf home range core, primarily by pregnant females. Our analysis goes beyond habitat selection to capture how moose alter their activities based on their environment. Our findings, along with climate change forecasts, suggest that moose in this area will be required to further alter their activity patterns and space use in order to find sufficient forage and avoid heat stress.

PHASE STRUCTURES AnD TRAnSITIOn BEHAVIORS OF A TRIPHEnYLEnE DISCOTIC LIQUID CRYSTAL

Chinese Journal of Polymer Science 2007年第1期25卷 57-71页

作者： Kwang-Un Jeong Alexander J.Jing Bart Mansdorf Matthew J.Graham Frank W.harris 程正迪 Maurice Morton Institute and Department of Polymer Science The University of AkronAkronOhio 44325-3909USA

The phase behaviors and structures of a triphenylene-derived discotic liquid crystal （LC） hexa-n-octoxyl- triphenylene （C8HET） were studied using the combined techniques of differential scanning calorimetry （DSC）, wide angle X-ray diffraction （WAXD）, selected area electron diffraction （SAED） and polarized light microscopy （PLM）. Onedimensional （1D） powder WAXD results at different temperatures coupled with DSC and PLM observations revealed that the C8HET compound possessed an LC phase and three different crystalline （K3, K2 and K1） phases below the isotropic （I） melt. The I←→ LC phase transition was thermodynamically reversible and independent of the heating and cooling rates. The development and experimental observation of the three crystalline phases relied on different thermal histories. Among the three crystalline phases in CSHET, the K3 phase is the most stable phase, while the K2 and K1 phases are metastable. note that the K1 phase only formed via a quenching process. Oh the basis of structure sensitive diffraction experiments such as 2D WAXD of oriented samples and SAED of single crystals, detailed structures and molecular packings of these four ordered phases were identified. The LC phase exhibited a hexagonal columnar phase with 2D lattice dimensions ofa = b = 2.38 nm and γ= 120°. All the three crystalline phases possess monoclinic unit cells, yet the y angle is not 90° in the cases of the K2 and the K3 phases, while in the case of the K1 phase the a angle is not 90°.

近来应用设计的一种固相放射免疫试验检测抗心脂抗体,我们报告了在96例慢性自身免疫性血小板减少性紫瘢(AITP)病人有30例存在抗心脂抗体,14例病人有升高的 IgG 抗心脂抗体水平,27例有升高的 IgM 抗心脂抗体水平。我们指出这些抗体通过与血小板膜上的磷脂结合介导周围血中的血小板的破坏,也可以推想,由于这些抗心脂抗体的存在,可以选出能继续发展成其它自身免疫性疾病,例如,系统性红斑性狼疮的慢性 AITP 的病人亚群。

Endoscopic ultrasound staging for early esophageal cancer: Are we denying patients neoadjuvant chemo-radiation?

AIM To evaluate the accuracy of endoscopic ultrasound(EUS) in early esophageal cancer(EC) performed in a highvolume tertiary cancer center. METHODS A retrospective review of patients undergoing esophagectomy was performed and patients with c T1 n0 and c T2 n0 esophageal cancer by EUS were evaluated. Patient demographics, tumor characteristics, and treatment were reviewed. EUS staging was compared to surgical pathology to determine accuracy of EUS. Descriptive statistics was used to describe the cohort. Student's t test and Fisher's exact test or χ~2 test was used to compare variables. Logistic regression analysis was used to determine if clinical variables such as tumor location and tumor histology were associated with EUS *** Between 2000 and 2015, 139 patients with clinical stage Ⅰ or Ⅱ?A esophageal cancer undergoing esophagectomy were identified. There were 25(18%) female and 114(82%) male patients. The tumor location included the middle third of the esophagus in 11(8%) and lower third and gastroesophageal junction in 128(92%) patients. ninety-three percent of patients had adenocarcinoma. Preoperative EUS matched the final surgical pathology in 73/139 patients for a concordance rate of 53%. Twenty-nine patients(21%) were under-staged by EUS; of those, 19(14%) had unrecognized nodal disease. Positron emission tomography(PET) was used in addition to EUS for clinical staging in 62/139 patients. Occult nodal disease was only found in 4 of 62 patients(6%) in whom both EUS and PET were negative for nodal involvement. COnCLUSIOn EUS is less accurate in early EC and endoscopic mucosal resection might be useful in certain settings. The addition of PET to EUS improves staging accuracy.
